const        XorKey:array[0..7] of Byte=($B2,$09,$AA,$55,$93,$6D,$84,$47); //字符串加密用 function Dec(Str:String):String;//字符解密函?vari,j:Integer;beginResult:='';j:=0;for i:=1 to Length(Str) div 2 do    begin      Result:=Result+Char(StrToInt('$'+Copy(Str,i*2-1,2)) xor XorKey[j]);      j:=(j+1) mod 8;    end;end;

就上面几行代码,
求懂php的帮忙把这个函数翻译成php的,
我delphi加密,然后php解密,


我对php一点也不懂,但是懂调用。


回复讨论(解决方案)

解决了200分奉上

还有一个帖子也是100分: http://bbs.csdn.net/topics/390998635

给个密文,我测试看看~

<?php$XorKey = array(0xB2,0x09,0xAA,0x55,0x93,0x6D,0x84,0x47);function Dec($str){	global $XorKey;	$result = "";	$j = 0;	for ($i = 0; $i < strlen($str)/2 - 1; $i++)	{		$result = $result . chr(hexdec($str[$i*2] . $str[$i*2+1]) ^ $XorKey[$j]);		$j = ++$j % 8;	}	return $result;}
Copy after login

function Dec($str){  $XorKey = array(0xB2,0x09,0xAA,0x55,0x93,0x6D,0x84,0x47);  $result = "";  for($i=0, $j=0; $i<strlen($str); $i+=2) {    $result .= chr(ord($str{$i} ^ 0) . chr(ord($str{$i+1}) ^ $XorKey[$j]);    $j = ++$j % 8;  }  return $result;}
Copy after login

能顺便把加密函数也翻译一下吗

function Enc(Str:String):String;//字符加密函? ?是用的一??或加密
var
i,j:Integer;
begin
Result:='';
j:=0;
for i:=1 to Length(Str) do
begin
Result:=Result+IntToHex(Byte(Str[i]) xor XorKey[j],2);
j:=(j+1) mod 8;
end;
end;



好测试密文

密文 F76DC321A1 解出来应该是Edit2 但是用你翻译的php的解出来是Edit 少了一位

<?php$XorKey = array(0xB2,0x09,0xAA,0x55,0x93,0x6D,0x84,0x47);function Dec($str){    global $XorKey;    $result = "";    $j = 0;    for ($i = 0; $i < strlen($str)/2; $i++)    {        $result = $result . chr(hexdec($str[$i*2] . $str[$i*2+1]) ^ $XorKey[$j]);        $j = ++$j % 8;    }    return $result;}echo Dec("F76DC321A1");

这样肯定没问题了。

$XorKey = array(0xB2,0x09,0xAA,0x55,0x93,0x6D,0x84,0x47);echo $s = enc('Edit2', $XorKey), PHP_EOL;echo dec($s, $XorKey);function Enc($Str, $XorKey) { //:String;//字符加密函?   ?是用的一??或加密  $Result = '';  $j = 0;  for($i=0; $i<strlen($Str); $i++) {    $Result .= sprintf('%02X', ord($Str{$i}) ^ $XorKey[$j]);    $j = ($j+1) % 8;  }  return $Result;}function Dec($str, $XorKey){  $result = "";  for($i=0, $j=0; $i<strlen($str); $i+=2) {    $result .= chr(hexdec($str{$i} . $str{$i+1}) ^ $XorKey[$j]);    $j = ++$j % 8;  }  return $result;}
